Specification of Letters Patent.

Application filed May 4, 1911. Serial No. 625,059.

To all whom 'it may concern Be it known that I, CHARLES E. GEIGER, acitizen of the United States, residing at Louisville, State of Kentucky,new and useful Improvements in Driers,

have invented certain of which the following is a specification.

` discharge it from the other.

This invention relates to driers more particularly designated anddescribed as rotary driers, comprising a rotatable cylindrical member inwhich a number of steam pipes are positioned, and being adapted toreceive the'materal to be dried at one endvan'd to In the accompanyingdrawings,-Figure 1. is a longitudinal sectional view of the preferredembodiment of my invention. Fig. 2 is a cross sectional plan viewthrough the manifold in the dischargeend of the cylinder. Fig. 3 is adetail view of one of the deflector plates positioned in the discharge.endof the cylinder.

Driers Yof this class are employed to remove themoisture .from grains,'herbage and the like, and when used to dry grasses or herbs, it isnecessary to make somev provision for the disposal of the stems orparticles which are too large to pass readily between the tubes, andwhich tend to clog up'the passage-ways unless theyl are ejected from thecylinder. .The cylinders are generally provided fth apertures nearoratthe discharge end thereof through which the smaller particles orgrainsl may pass, and the present invention has for itsobject moreparticularly to provide means v'to eject material through the end of thecylinder between the spokes of the manifold. It is also necessary whentreatin grasses or the like, to provide anentrance c amber, in which thestems or larger'particles may not become clogged between the tubes ofthe drier. The central drying tubes are therefore shortened in this inthe countyof Jefferson andV 'an axial chamber 19 and four spoke-likeend' of the cylinder. Referring now more particularly'to the drawings, acylinder 6 is provided at one end with a ange T slightly larger indiameter than the cylinder and having communication with the cylinder bymeans of openings 8 in the walls thereof, and at the other end withv amanifold 9 to which is secured a ange 10. The cylinder 9 is adapted tobe mounted by means of these ianges 7 and 10 so that it may be rotated.labout an axis through its center, suitable bases 1l and l12 being provided at the ends with means rotatably to mount the cylinder thereon.Any suitable driving means maybe employed to rotate .the cylinder uponits bases. In thepresentexemplication'of the invention, the flange 10isprovided with teeth which. mesh with the teeth ina pinion 13 mounted on,a shaft 14 and having suitable gears 15 in connection with the shaft toeect the rotation of the pinion 13 and ofthe cylinder 6. One end of thecylinder will be hereinafter designated as the inlet end and the otheras the discharge end. The discharge end is provided with a manifold 16secured tov the-cyl inder 6 and having a plurality of tubes 17 securedin Jthe manifold through the inner side and communicating with theinterior thereof. This manifold is shown in section in Fig.' 2, and Ainthe form shown is provided with four peripheral chambers 18,

connecting portions 2Q between the axial chamber and the peripheralchambers,

although it is to be understood that 4any del sired number of peripheralchambers may be employed. Each peripheral chamber is conL nected fromits forward end (assuming the direction of rotation of the cylinder tobe in a clock-wise direction) with a passage 21 which communicates withthe interior of the Patented Feb. 11, 191s.

drier to provide a greater space at the inlet sol axial chamber 19.' Therear end of each pe.-

ripheral chamber is closed from. such communication and is lprovidedwith a pipe 22 which extends adjacent -the center of the axial chamber19 and from there extends v outwardly into a chamber 23 which is securedto the manifold and is adapted to re'- ceive the water of condensationwhich may be delivered by thesaid pipes 22. This chamber 23 is formedwith an enlarged portion 24 into which thewater of.' condensation fromthe pipes 22, is collected, a removable i plate 25Xbeing provided'tocover an opening into the said chamber. A steam pipe connection 26 isadapted to be inserted inthe end of the chamber 23, and suitable packing'devices 27 are provided to make the connection between the steam pipeconnection 26 and the chamber 23 substantially steamtight. This steampipe connection 26 is provided with openings in theends through which apipe 28 extends, the inner end of the pipe being adapted to extend alsothrough the chamber-23 and into the axial chamber 19 of the manifold.Inserted in the steam pipe connection 26 and having communication withthe ,hollow interior thereof are tubes 29 and 30, the latter of which ispositioned so as to project into the enlarged portion 24 of the chamber23 while the former is adapted to afford communication between theinterior of the steam pipe connection 26 and the exhaust connection.This exhaust -may be either ic the atmosphere, to a waste pipe or drain,or to a steam trap, whichever is desired. In the outer surface of themanifold 16 and opposite the ends of the tubes opening into the manifoldare removable plugs 31, which are adapted to afford communication withthe interior of the manifold adjacent the ends of the tubes 17. Theaxial chamber 19 is also provided in the present exemplification of theinvention with a number of tubes 32, which are secured in the inner faceof the said chamber and which extend toward the outer end of thecylinder. These tubes are provided at the other'end with removable plugs33 which are adapted to close the ends o the tubes and are-adjustablefor the purpose of allowing fluid to escape from the tubes. These tubes32 do not extend to the inlet end of the cylinder 6 and are supportedintermediate of the ends by means of the perforated plate 34, which ispositioned in the cylinder by means of rods 35 extending through theshell thereof and secured by nuts 36 orfother suitable means. Thedischarge end of the cylinder is also provided with a housing 37preferably secured to the flange portion 7 extend-` ing beyond themanifold and providing a conveying means for material which escapes fromthe cylinder through the openings 8 adjacent the end of the cylinder. Byreference to Fig. 2 it will be seen that the opening 8 extends aroundthe manifold 16 on all sides, permitting the continuous escape ofmaterial from ille cylinder through the said opening when the cylinderis rotated.

Extending inwardly from the manifold 16 and positioned between the pipes17 and the pipes 32 are deflectors 38. These deflectors may be formedintegrally with the manifold, or may -be attached thereto in anysuitable manner, and are formed wit-h a wide mouth portion 39 narrowinggradually toward the base to form a scoop or deliecting plate so that asthe cylinder is rotated, the material I inside the cylinder and adjacentthe discharge end will be scooped into the deflectors 38 and will beejected from the cylinder through the end thereof between the spokes ofthe manifold 16, falling into the project- .ing part of the housing 37.

A conveyer 40 is positioned at`the discharge end of the cylinder and asthe cylinwhich is also provided with plugs 31 similar to the plugs inmanifold 16. A 'feeding hopper 41 1s also provided at the inlet end ofthe cylinder in the bottom of which is a spiral conveyer 42 adaptedtoconvey material from the hopper into thev inlet end of the cylinder 6,and separated from the hopper by a partition 43 is a vapor passage 44through which vapors arising from the heated material in the cylindermay escape therefrom. Any suitable driving means may be employed torotate the conveyer 42, it

being found that the material lmust be fed to the conveyer at differentspeeds, depend ing upon the kind of material to be dried.

A yoke 45 connected to the manifold 9 extends toward the hopper andforms a retaining shield for preventing the loss of material at theinlet end of the cylinder and also to prevent the escape of vapors inany vother way than from t-he vapor passage 44.

It is evident that when the drier is used to dry herbage and the like,the stems or particles that are too large to pass between the tubes 17and out of the cylinder by way of the discharge openings 8 will bedeflected by 'the deectors 38 and ejected from the cylinder, thuspreventing the stems from clogging the discharge. end of the cylinderand preventing the discharge of the dried material. The openings 8 maybe omitted if desired.' It will also be seen that with the applicantsconstruction an enlarged chamber is formed at the inlet end of thecylinder by reason of the tubes orpipes 32 extending only part ofthe waytoward the inlet end, thus forming a central space or chamber in .theinlet end, thereby preventing the material which is fed tothe drier fromclogging this end of the drier.-

Steam or other drying liuidis admitted to the manifold 16 through'thepipe 28 and the tubes 32 are freely mounted at -t-heir other ends `topermit them to extend longitudinally, independently of the other tubes20 rotated.

Locaceo 'the enlarged portion 24 of the chamber 23 j and is dischargedtherefrom through the steam pipe connection 26 and thepipe 29.

If this ipe 29 is connectedto a ste-am trap, the disc arge'of water isautomatic, but any desired means of discharging this water may beemployed.

I desire not to be limited to the exact construction, combination andarrangement of theseveral parts of my invention for it is evident thatthose skilled in the arts to which this invention pertains may makevarious changes therein without departing from the spirit and scope ofmy invention.
